REPAIR INFORMATION
To perform a problem-free and successful steering gear repair, extreme caution and cleanliness, as well as properly functioning tools are an important requirement. Understandably, general safety guidelines apply when performing repairs.
A series of applicable general notes for individual repair procedures - otherwise listed several times at many points in the repair information - has been collected here. They apply for this repair information.
| CAUTION | The suspension components could be damaged. If the subframe mount, the steering gear or the subframe crossbrace are not installed correctly, do not rest the vehicle on its wheels. The vehicle must not be supported on the subframe or the subframe crossbrace (for example using a floor jack). |
| WARNING | All bolts and nuts must be tightened properly before driving the vehicle! |
| WARNING | Danger of personal injury caused by the engine starting automatically on vehicles with the Start/Stop System. When the Start/Stop System is on (recognizable by a message in the instrument cluster), the engine may start automatically. Make sure the Start/Stop System is off whenever working on the vehicle. Turn off the ignition and turn it back on only when necessary. |
STEERING GEAR
- Thoroughly clean connecting points and their surrounding areas before loosening.
- Place removed parts on a clean surface and cover to prevent contamination. Use foils and paper. Only use lint-free cloths!
- Only install clean components: Only unpack replacement parts immediately prior to installation.
- Use exclusively lubricants and sealants marked with part numbers.
- Carefully cover or seal open components, if repairs are not carried out immediately.
SEALS, SEALING RINGS
- Always replace seals and gaskets.
- After removing seals/boots, inspect the contact surfaces on housings and shafts for burrs and damage and repair if necessary.
- Remove all residual sealant of fluid seals from sealing surfaces, no sealant residue must enter the steering gear housing when doing this.
Scheme 142
- Loosen and tighten the bolts and nuts of covers and housings in a diagonal sequence.
- Components that are extremely sensitive must not be distorted and should be loosened and tightened in stages in a diagonal sequence.
- Tightening specifications for unlubricated bolts and nuts are given.
- Always replace self-locking nuts and bolts.
- Always replace the bolts and nuts, which are tightened with an additional tightening angle.
ELECTRICAL COMPONENTS
Surely everyone has been shocked at one time or another when coming into contact with a metal object. The reason for this is the build-up of static electricity in the human body. This charge can lead to functional problems by touching the electrical components of steering gear.
Touch a grounded object - for example a water pipe or a vehicle hoist - before working on electrical components. Do not make direct contact on connector terminals.
STEERING, BLEEDING AFTER REPLACING
After steering system reconstruction, system must be bled differently depending on extent of reconstruction.
Bleed after replacing entire steering system or replacing steering gear
Fill the reservoir completely.
Lift the vehicle just enough so that all the wheels are off the ground.
- Engine turned off
Turn steering wheel from lock to lock 10 times, with engine switched off.
Fill the reservoir completely.
Briefly start engine (max. 2 seconds).
Pump must not draw in any air. Steering wheel must not be turned under any circumstances.
Approximately 30 seconds wait between individual engine starts.

Bleeding after replacing a component in the steering system, except for the steering gear
Inspect hydraulic oil level and fill as needed.
Briefly start engine (max. 2 seconds).
Pump must not draw in any air and steering wheel must not be turned under any circumstances.
Approximately 30 sec. wait between individual engine starts.
Inspect hydraulic oil level and fill as needed.
Repeat this process until oil level remains constant.
Start the engine and allow it to run 2-3 minutes, do not turn the steering wheel.
Any air remaining in the steering system will dissipate by itself when driving over the next 10 to 20 km.
POWER STEERING FLUID LEVEL, CHECKING
Do not run engine and turn front wheels to straight ahead position.
Fluid cold (approximately 20 °C (68 °F))
Remove the cap.
Wipe dipstick off with a clean cloth.
Screw cap on hand-tight and unscrew it again.
Note. The cap must be fully screwed in order to obtain an accurate fluid level reading.
Check the fluid level: Oil level must be within the -A- area.
Scheme 143
Fluid at operating state temperature (approximately 80 °C (176 °F))
Remove the cap.
Wipe dipstick off with a clean cloth.
Screw cap on hand-tight and unscrew it again.
Note. The cap must be fully screwed in order to obtain an accurate fluid level reading.
Check fluid level: Oil level must be within area -B-.
Note. Fluid must be drawn off if the level is above the specified range. If oil level is below aforementioned area, then the hydraulic system must be checked for leaks. It is not enough to just add fluid. Do not use drained hydraulic oil.

VEHICLES WITH DYNAMIC STEERING OVERVIEW (6-CYLINDER FSI ENGINE)
Vane pump is not designed to be serviced. If there are customer complaints, the cause must be determined using a pressure and leak test. If there is a malfunction, replace the vane pump.
Note. If power steering fluid is low in reservoir, check steering system for leaks. If there are leaks in the area of the line connections, the lines/connections must first be inspected for leaks, tightened as necessary and wiped dry. Power steering pump is delivered without oil. Therefore, hydraulic oil must be filled before installation and turned by hand. Otherwise, noises when driving or damage to power steering pump may occur.
